A few tricks for your Illusionist.  As with all things illusionary, GM rulings may vary

1.)  Illusory Self will cause any one attack to automatically fail.  Major Image cast with a 6th level slot lasts until dispelled and does not require concentration.  Alternatively, Programmed Illusion can be used.  These can be combined. When you are attacked, you can make it seem that your Illusory Self was activated even if it has already been activated.  You can cause an illusion of yourself to react as if attacking it activates Illusory Self.  In other words, cast an illusion of yourself.  When that illusion is attacked by an enemy, the attack will go right through the illusion and give the attacker reason to believe it just attacked an illusion.  However, if your illusion  reacts as if illusory self was activated, then the fact that the enemy's attack had no affect can now be justified.

Now, consider,  every time the enemy attacks you or an illusion of you, it appears that illusory self is triggered. This can make it really difficult for the enemy to know what to attack.  Note  that when he manages to actually hit you, the feel of striking flesh can inform him that he isn't hitting an illusion.  However, see trick #2

2.) Misty Step + Programmed Illusion   Set up Programmed Illusion to leave an after image of you behind when you cast Misty Step.  After you are attacked in melee, cast Misty Step and leave an image of yourself behind.  You might Misty Step behind a rock so you can't be seen.  The attacker will continue attacking the illusion you left behind never realizing that you are no longer there.

3.) Pseudo Mirror Image.  Make an illusion of "yourself under the affect of Mirror Image."   When the attacker hits the illusion, the attack will go right through the illusion and that will alert the attacker of the illusion. Simply respond to that by causing one of your mirror images to disappear.  

4.) Remember that Creation is an Illusion spell and is, therefore, subject to Malleable Illusions.  

5.) Consider mixing illusions with reality.  For example, stand behind a real wall (perhaps created with trick #4) and then cast Minor Image in front of that real wall.   When enemies fire ranged weapons at you, those attacks will go through the illusion and the enemy will believe that they can hit you.  What they won't see is that their attacks are bouncing off the real wall which is behind that illusion

6.)  Invisibility + Major Image @6th   (or Programmed Illusion).  A variation on trick #2 above, this can serve as a poor man's Mislead.  Further, the invisibility can be upgraded to Improved Invisibility

7.) Because of the sheer diversity of Malleable Illusions, Contingency + Major Image can be an attractive combination

It has been my goal here to avoid copying tricks I've seen elsewhere.  So, hopefully, these are new to the 5e community.

 1) Major Image doesn't work like that. You cast into an area and it stays there. It requires an action from you to move it around, and an illusion cannot take reactions. You cannot have a major image create another illusion. You could make it appear so using Malleable Illusions but that requires an action from you. You could use a ready action to do this, which takes your reaction. Even then, the illusion is a singular thing. You can't use major image to create two creatures, for instance. This doesn't work. Even if the DM lets it, you're using a lot of action economy for very little. 

2) You seem to be forgetting programmed illusion is set into an area and doesn't travel with you. Once cast into effect, you cannot move it. Malleable Illusions lets you change the program, but not the placement. You cannot cast this and misty step in same turn. Better off just casting Mislead instead - does the same thing, basically, and uses only 1 slot and is actually valid.

3) This involves multiple creatures being created using major image, which is beyond what the scope of the spell allows. Invalid. 

4) Correct. Finally you got something right here. I was getting worried.

5) Also valid. Yay. 

6) As mentioned, Trick 2, doesn't work. This won't either for the same reasons. 

7) Contingency and Major Image cannot be combined. Major Image targets an area. The spell used for contingency must target you and only you can be affected by it. You can't use major image, for the same reason you can't use fireball. You could use Mislead, however, or Invisibility or Mirror Image or such as. You can use spells that could target multiple creatures, but it would still only affect you (such as Waterbreathing, for example).

This is a good effort but you seem to fail to understand the limitations of spells like major image and programmed illusions and rely on using them in ways they cannot be by RAW.

This is a good effort but you seem to fail to understand the limitations of spells like major image and programmed illusions and rely on using them in ways they cannot be by RAW. 

1.)  "It requires an action from you to move it around, and an illusion cannot take reactions."  True, but irrelevant.  A Programmed Illusion can be moved around without an action and can take reactions.  Also, both Programmed Illusion and Major Image (cast @6th level) are concentration-free.  That means that you can keep several of them up at the same time indefinitely.  

2.) "programmed illusion is set into an area"  That's a house rule.   You may argue that it is RAI, but it certainly isn't RAW.  And I'm not the first one to point that out.  Treantmonk, for example, goes into it.  "You cannot cast this and misty step in same turn"  True, but you can Malleable Illusions and Misty Step in the same round.   In other words, if you cast an illusion (for example, of a monster) in round 1, you can then repurpose that illusion in round 2 to create an illusion of yourself in your old location as you Misty Step.                                        

3) Mirror Image is an affect, not a creature.  An illusion of you with Mirror Image is one illusion (you with Mirror Image).  It is no different than an illusion of you with Resilient Sphere or an illusion of you with Fire Shield.

7.) You got one right.  I stand corrected.

NOTE: As I prefaced the original post, everything depends on your GM.  That having been said, Cybermind asserted several things as rules which are actually not RAW.  I'm glad that he gave his input as it shows some push back you might get from the GM misunderstanding what is RAW.

Below, I'll show that my interpretation of Programmed Illusion is supported by RAW.  Other interpretations are possible.  It is up to your GM.

Per the description of Programmed Illusion

You create an illusion of an object, a creature, or some other visible phenomenon within range that activates when a specific condition occurs. The illusion is imperceptible until then. It must be no larger than a 30-foot cube, and you decide when you cast the spell how the illusion behaves and what sounds it makes. This scripted performance can last up to 5 minutes.

Per the description of Malleable Illusion

Starting at 6th level, when you cast an illusion spell that has a duration of 1 minute or longer, you can use your action to change the nature of that illusion (using the spell's normal parameters for the illusion), provided that you can see the illusion.

So,

round 1: You cast Programmed Illusion at area 1.   Note that area 2 is not in range.

round 2: You move to a new location and now area 2 is in range.  You can use your action to change the nature of the illusion using the spell's normal parameters.  Since area 2 is now in range, the illusion will meet all the spell's normal parameters.

Within range 120 ft, 30 ft cube. 

That's an area.

You'll see the same target for all other area-target spells. 

So, no you cannot move the illusion around as you want. This isn't a houserule - it's the raw. See how spell targeting works. Malleable illusion changes the nature of the illusion (what the illusion is of), it doesn't let you move it (part of the targeted casting). You have provided nothing to state it does other than bad comprehension of words.

 I'm not going to argue with you.  If you don't cite the relevant rule, then there's nothing to discuss.

Programmed Illusion:

"You create an illusion of an object, a creature, or some other visible phenomenon within range that activates when a specific condition occurs. The illusion is imperceptible until then. It must be no larger than a 30-foot cube, and you decide when you cast the spell how the illusion behaves and what sounds it makes. "

So, you target somewhere within the range and from that point you can make an illusion up to 30 ft cube. You can decide what illusion occurs in that space.

From Spellcasting in the Targets subsection:

"A typical spell requires you to pick one or more targets to be affected by the spell's magic. A spell's description tells you whether the spell targets creatures, objects, or a point of origin for an area of effect (described below)."

The programmed illusion targets a point of origin in an area of effect - in this case a cube, with the point of origin being within 120 ft.

There is nothing in the spell that says you can move it around. Compare to Major Image which lets you do so with an action. 

Malleable illusions lets you change the nature of the illusion. This is the "illusion of an object, a creature, or some other visible phenomenon" part. It doesn't let you recast or retarget it, that isn't the nature of the illusion, targeting is part of the spell casting (see Spellcasting section and Targets).

Now, you do you in your games, but the RAW is clear.

Perhaps you should read Chapter 10 (Spellcasting) of the PHB (or Basic Rules) again? You're missing some points.

This is the "illusion of an object, a creature, or some other visible phenomenon" part.

What's the RAW that says that?

The fairly ******* obvious use of "nature of illusion" instead of "nature of the spell".

Jesus ******* christ, dude.

 You're making assumptions not supported in the RAW,

As I said, I don't want to argue with you. Unless you cite RAW, there's nothing to discuss.

 Easy friend, it's just an online discussion.

Saying RAW isn't RAW is weird. You do you.

But for anyone interested: these tricks fail.

And for DMs be careful about houseruling as Wren suggests. Because a permanent, portable Programmed Illusion means the wizard never has to bother with casting another illusion spell again. It's broken AF and will definitely bite you in the ass in a decidedly not-kinky way. This will also upset other plays who have to spend resources for their abilities while the wizard no longer needs to as they can just move and reuse programmed illusion as much as they want, never having to spend a spell slot on such ever again, forever. 

Yes, as you can imagine that's ridiculously and atrociously silly, but it's what Wren would have you believe (incorrectly) is how the spell works.

1.) You've so far failed to cite any RAW I'm contradicting.   You  are  making attacks now precisely because you know there's no RAW that I'm contradicting.

2.) The Illusionist is spending resources.  This applies only to illusions.  It also takes an action to use.  

3.)  When you compare this to the free teleport that Conjurors get or the large number of free spells that Diviners get, it isn't unbalanced.

1) I have cited RAW. You're just saying it isn't. Which is frustrating. I've referred to the spell, the rules on spellcasting and targeting, and more. I've mentioned RAW in every post that explains my view. It directly contradicts you and is RAW. You are simply stating that I'm not, it's the equivalent of sticking fngers in ears and going "lalala" pretending you don't hear. 

2) Using an action is not spending resources. Resources are things like spell slots, sorc points, ki, etc. 

3) It is very unbalanced. A better comparison is using a permanent major image and bringing that around with you - which is RAW and balanced. Programmed Illusion is lot more powerful than Major Image. See the conjurer's benign transposition is limited, as it is no better than a 2nd level spell and they have to spend resources to keep using it. Diviners also have to spend higher slots to get back lower ones and they need to use divination spells which there's considerably less of and with limitations on their casting. Programmed Illusion is a very powerful illusion from a 6th level slot and requires no further expendable resources ever again. No, the comparison isn't even remotely close.

You keep stating you won't argue with me until I cite the raw, saying I haven't. Yet.. You keep replying to argue which kinda implies you've either recognised I actually was or you were lying about not arguing. Neither is a good look on you. 

1.) You claimed, "This is the "illusion of an object, a creature, or some other visible phenomenon" part."   Where does RAW actually say that, though?  It doesn't.  "you can use your action to change the nature of that illusion (using the spell's normal parameters for the illusion)" doesn't actually say that "nature of that illusion" doesn't include Area of Effect.

2.) Actions are the most valuable of resources as they are a measure of what you can do (one thing per action)

3.) Illusions are shut down by spells and effects like True Seeing which are a lot more common than anything that'd block Benign Transposition.
